Boiler maintenance and cleaning checklist

Ensuring that your boiler runs smoothly is integral to keeping your home warm throughout the year. But many people don’t take appropriate care for their boiler, which can decrease efficiency and lead to further problems in the long run.
Below you’ll find a handy boiler maintenance and cleaning checklist that will take you through the essential tasks you will need to carry out to keep your system in great condition.
Please note: The information listed below is meant as a general guide to boiler care and maintenance. Any servicing or in-depth maintenance works must be carried out by a Gas Safe registered engineer with a calibrated flue gas analyser and manometer.
Here is what you can do each week, month, and year to keep your boiler running smoothly.

Weekly boiler maintenance and cleaning checklist

To ensure your boiler is running smoothly and to prevent any long-term problems, it’s wise to take the time to check on it every week or two. These are quick checks that can be done in a matter of minutes, but could help you identify a problem before it has a chance to get any worse.

  • Be aware of warning signs: If you notice any leaks, cracks, noises or black marks, you probably have a problem. Check for these signs each week as the sooner you detect and repair a fault, the less chance it has of getting worse.
  • Check the boiler and pipes for leaks: If your boiler or pipework is leaking, this could indicate a serious fault, so you want to know about it straight away. Check your boiler controls for any leaks, as well as your pipework — particularly around the joints.
  • Listen for noises and vibrations: You should also check whether your boiler is making any strange noises or is vibrating excessively, as this could indicate it is being overworked. If this is the case, call a Gas Safe registered engineer.
  • Avoid clutter: Boilers need plenty of ventilation to operate smoothly, so it’s wise to avoid surrounding it with clutter, such as coats, shoes, and bags. If your boiler is boxed in, make sure the space around it is clear and that the door is easily accessible.

Monthly boiler maintenance and cleaning checklist

Aside from the daily checks, there are other things you can do on a monthly basis to ensure that your boiler lasts for as long as possible. By following these tips and taking the time to understand your boiler, you could get many more years out of it.

  • Basic cleaning: Over time, dust and grime can build up around your boiler and pipes. For general cleaning, you can use a brush and vacuum the exterior of your boiler, including any pipe work. Anything more in-depth should be carried out by a Gas Safe registered professional.
  • Repressurise your boiler: Keep an eye on your pressure gauge to ensure your boiler is at the correct pressure. If the pressure is too low, usually lower than 1 bar, you will need to repressurise your boiler.
  • Bleed your radiators: If your boiler pressure is too high, you will need to release some of the pressure by bleeding your radiators. If the pressure increases again, we recommend contacting a Gas Safe registered engineer.
  • Check the flame: Your boiler’s pilot light should be strong and show a clear blue flame. If the pilot light seems to be yellow or smoky, there could be something wrong and you should call a Gas Safe registered engineer. You can find out more in our how to relight your pilot light guide.
  • Turn the heating on: To run smoothly, boilers must be used regularly. It is recommended that you turn your heating on for 10 or 15 minutes every couple of weeks during the summer months in order to keep the boiler ticking over.

Yearly boiler maintenance and cleaning checklist

While most of your boiler maintenance and cleaning should be done regularly, there are some things that only need to be done once a year.

  • Lag your pipes: Ahead of the winter months, you should check all your pipe lagging to ensure it is intact. Pipes can freeze when the temperature drops, cutting out the boiler. You can prevent this from happening by insulating your pipes with lagging or by turning the heating on regularly throughout the cold months.
  • Annual servicing: To keep your boiler in top condition, it is recommended that you have it serviced every year by a Gas Safe registered engineer, even if everything seems to be in working order. The engineer will check all the parts and clean the internal components. Sign up for homeowner boiler cover with All England Gas and you can rest assured knowing your boiler maintenance and cleaning will be taken care of.
